1. A temperature compensated voltage reference circuit, comprising:

  • (a) means for producing an output voltage at an output terminal comprising a reference voltage device connected between a predetermined voltage potential and the output terminal, such reference voltage device producing a reference voltage varying with temperature over a predetermined range temperatures; and

    (b) means, responsive to a compensating current, for producing a compensating voltage in series with the reference voltage, such compensating voltage varying inversely to the voltage variation of the reference voltage over the predetermined range of temperatures, such compensating current passing serially through the reference voltage device and the compensating voltage producing means.
